Non-combat pets have no special abilities, although they have funny animations and sounds.
Hunter pets can be good tanks, dps or pvp pets depending on what kind of pet you tamed and how you spend your talents.

Death Knights also have pets, including the Ghoul, Army of the Dead and the Gargoyle, again depending on how the players spends the talent points.
